Not sure if it belong in this sub-forum but Tartiflette convinced me so.
I know the skills trees are going to be reworked in the future, possibly their perks as well. But hey, maybe it'll give some ideas for Alex and the modders.
I have been thinking of the ability to deploy ships from the sides, like in pursuit scenarios but in a normal battle. Could add some pretty fun tactical possibilities. It is very strong however, probably a level 10 perk. It would clearly fit for the Advanced tactics skill. It is currently pretty much useless to skill it past 5 so at least it'll give an incentive to reach 10 with this new perk.
Alternatively, the possibility to deploy destroyers (and bigger?) from the sides during pursuit scenarios. Could be very handy with fast destroyers like the Medusa.
Another idea, not as serious though, a perk that reduce the cooldown on ship systems. Would rather fit for the combat skills. The Power Grid Modulation one maybe? That would be pretty damn powerful though, even a 25% bonus at level 10. Off the top of my head, the Hyperion would be the one that benefit from the most. Would wreck the balance for some mods though.
If you have some more ideas.
